i did research for hours and now i have to post my question(s) in here....

i came from 20180908 ESPEasy Mega and did an upgrade to 20180910 because i need to send HTTP messages back to controller.....

Hardware is an NodeMCU Lolin.
The image i took was "normal,4096"

After upgrade all generic system tasks were not working at all (like uptime for example)
minute uptime counter stays at "0" for example.

When i go back to 20180908 all system infos are working again.

Now i did setup a fresh new NodeMCU Hardware and used 20180910 from the beginning. All works great.

Only my other NodeMCU ist not working.

QUESTION: How can i start from scratch ?
i did press "factory reset" at the web gui.......
i did flash a simple blink sketch...

but always i flash an ESPEasy MEGA version all my settings are still there, like ethernetconnection, tasks, rules...
Where there comming from ? EEPROM ?
So how can i DELETE ALL and bring the devive back to EMPTY ?
